7. In this review, ‘fuel decomposition’ refers to chemical consumption of the fuel by any chemical process.
8. The small aromatics are the compounds formed by the addition of the first new benzenoid ring.
9. The mechanisms of first ring addition are very sensitive.
Exercise 4. Translate the following sentences.
1. Atmospheric particles can be two types.
2. Fine particles are formed by chemical processes such as soot formation.
3. Exposure to fine particles can be very dangerous for environment and human’s health.
4. To prevent the negative impact of fine particles on people’s health the United States government has adopted new legislation.
